Fig. 4: Real-time estimation of joint angles.

Collection of hand poses conducted during the calibration (a) and the evaluation (b) for the joint angle estimation. c Graphical representation of the correlation between the joint angles (vertical) and the sensor signals (horizontal) in calibration dataset. d Plot of the time trajectories of the estimated and true joint angles for the large hand subject in the self-calibration group. T Thumb, I Index, M Middle, IP interphalangeal, PIP proximal interphalangeal, MCP metacarpophalangeal, CMC carpometacarpal, flex flexion, abd abduction.
